Once an alarm has been validated after one (or two) confirming
measurements, the subject can be moved away (>10 m) from the monitor,

the location(s) of the contamination or point source.
Note:
The red detector alarm light LEDs will offer guidance as to the
probably location(s) of the radioactivity on the subject.
